Ce. Ketley et Ma. Lennon, Determination of fluoride intake from urinary fluoride excretion data in children drinking fluoridated school milk, CARIES RES, 35(4), 2001, pp. 252-257
Twenty-four-hour urine samples were collected from each of thirteen 5- to 6
-year-old children both under customary conditions of fluoride intake (i.e.
usual diet including milk containing 0.5 mg fluoride and usual oral hygien
e procedures with fluoride toothpaste) and during a 4-day study period in w
hich their customary fluoride intake was replaced with standard fluoride do
ses. The 24-hour fluoride excretion under customary conditions of fluoride
intake was 0.30 mg and in response to fluoride doses in the range of 0.5-2.
0 mg it was in the range 0.26-0.61 mg. Using data obtained during the study
period for all subjects combined, the fluoride intake from all sources und
er customary conditions was estimated as 0.76 mg, representing a fractional
fluoride excretion of 39%. It is concluded that these children are possibl
y receiving suboptimal amounts of fluoride. Copyright (C) 2001 S. Karger AG
